Hollow Hills Elementary scores 58 of 100 on SchoolScope's Scope Score — the 80th percentile of 5,744 California elementary schools (CDE CAASPP 2025).

Measures test performance, attendance, and climate — not arts, community, or your kid. How we score →

💪 Strong All-Around — Ask about what we don't score — class size, electives, the feel of a classroom — strong numbers everywhere on paper don't mean every classroom feels the same.

Most rating sites would stop at “69% proficient” and call it done. Hollow Hills deserves a closer read. The school sits in Simi Valley, where one in three students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

Hollow Hills's low-income kids hit 61.2% proficiency in ELA — a number the same group reaches at 38.2% statewide. If you're trying to read past zip-code-driven test scores, that's the signal worth weighing.

Worth a school visit

Ask how the school challenges kids who clear the standard early. The gap between meeting and exceeding is where pacing shows.

  • Ask whether extra support — tutoring, counseling, small groups — reaches kids across income lines, not just the students already ahead.
  • Ask whether the tour can step into a working classroom — watch how the teacher handles a student who's stuck.
  • Ask to tour while school's in session, and notice how hallways and transitions feel — culture shows up between classes, not just in them.
  • Ask how the school communicates with families when a child starts to struggle.
  • Ask what a typical day looks like for a new student in the first few weeks.

Unlike single-number ratings, the Scope Score shows what drives the ranking so parents can decide what matters most to their family. See full methodology.

Is Hollow Hills Elementary getting better or worse?

Based on 2025 CAASPP data, proficiency at Hollow Hills Elementary increases by 0.4 percentage points from Grade 3 to grade 5 growth.
